Mechanical behavior of amorphous alloys
TL;DR: In this paper, a review of recent advances in understanding the mechanical behavior of metallic glasses, with particular emphasis on the deformation and fracture mechanisms, is presented, where the role of glass structure on mechanical properties, and conversely, the effect of deformation upon glass structure, are also described.

Difference in compressive and tensile fracture mechanisms of Zr59CU20Al10Ni8Ti3 bulk metallic glass
TL;DR: In this article, the authors investigated the fracture behavior of a Zr59Cu20Al10Ni8Ti3 bulk metallic glass under compressive and tensile deformation, and found that the fracture is mainly localized on one major shear band and the compressive fracture angle between the stress axis and the fracture plane is 43degrees.

Mechanical properties of bulk metallic glasses
TL;DR: In this article, the deformation and failure initiation mechanisms of bulk metallic glasses have been investigated, showing that brittle and plastic failure can create intricate fracture patterns, quite different from those observed in crystalline solids.

A microscopic mechanism for steady state inhomogeneous flow in metallic glasses
TL;DR: In this paper, an empirical deformation map for metallic glasses is introduced and the two modes of deformation, homogeneous and inhomogeneous flow, are reviewed, based on a dynamic equilibrium between stress-driven creation and diffusional annihilation of structural disorder.
Journal ArticleDOI
